 Hi there everyone.
 I had to change from spektrum radio to a chinese generic one. So we made a MeekPE PPM Encoder Board, with all set as the page of the enconder describes. but the PPM signal refuses to show up on pprz, we did some tests on the osciloscope and we could see the signals leaving the ppm board towards lisa. Any ideas on what might be wrong?

Airframe file:  
<subsystem name="radio_control" type="ppm"/>  
<define name="TELEMETRY_MODE_FBW" value="1"/>

<!DOCTYPE radio SYSTEM "radio.dtd">
<radio name="generic" data_min="800" data_max="2200" sync_min="5000" sync_max="15000" pulse_type="POSITIVE">
<channel ctl="D" function="THROTTLE" min="1000" neutral="1000" max="2000" average="0"/>
<channel ctl="C" function="ROLL"     min="1000" neutral="1500" max="2000" average="0"/>
<channel ctl="B" function="PITCH"    min="2000" neutral="1500" max="1000" average="0"/>
<channel ctl="A" function="YAW"      min="1000" neutral="1500" max="2000" average="0"/>
<channel ctl="G" function="SWITCH1"  min="1000" neutral="1500" max="2000" average="1"/>
<channel ctl="E" function="MODE"    min="1000" neutral="1500" max="2000" average="1"/>

ps.: channel 6 in the radio is supose to be the mode selector.
